He laboured because of the frame of thought his toil brought with it, but still more that he might be alone: that he might be able to point to his soiled hands, the shabby clothes which he wore when working with chemicals or at the forge, the sheets of paper covered with half-finished and maddening calculations, as an excuse why he should not be taken out, or, worse still, dragged from his home to stay for nights, or perhaps whole weeks, in other places.

If she had not been, she must have known that these were not chemicals, but explosives with which she proposed to play. The trouble was that Fanny Brandeis, the creative, was not being fed. And the creative fire requires fuel. Fanny Brandeis fed on people, not things. And her work at Haynes-Cooper was all with inanimate objects.

We cannot expect to obtain the conditions of the operating table on the battle-field, but chemicals which are effective in very small quantities or concentrations may find another channel into the human system.

"My idea is on a bigger scale. There's no reason, Ned, why a big fire in a tall building, like a sky-scraper, shouldn't be fought from above, as well as from below. Now if I had the right sort of chemicals I could " Tom paused in a listening attitude. There was the rush of feet and a voice cried: "I'll get them! I'll get the scoundrels!"

The vapor hissed as it rushed into the big bag overhead. Tom carried aboard his craft the chemicals needed to generate the powerful lifting gas, of which he alone had the secret. It was more powerful than hydrogen, and simple to make. The balloon of the Flyer was now being distended. Meanwhile Tom, with Koku, Mr. Damon and Mr.

Many checks may be altered to a larger amount by the mere addition of a stroke of the pen here or the erasure of a line, by means of chemicals, in some other place.

One of them offered him the use of a room in Gold Street, as a laboratory, and the other, who was a druggist, agreed to let him have such chemicals as he needed on credit.

Gas travels quickly, so you must not lose any time; you generally have about eighteen or twenty seconds in which to adjust your gas helmet. A gas helmet is made of cloth, treated with chemicals. There are two windows, or glass eyes, in it, through which you can see.

There is no lack of God's gifts on Mars. As intensive farming is a necessity on our planet, plant food or fertilizing elements are plentiful. One of the large white circular spots observed by your astronomers, located in a region on Mars named by them Elysium, and which has been a puzzle to all observers, is an immense deposit of fertilizing chemicals.

The atmosphere of that early day, filled with vast volumes of carbon, oxygen, and other chemicals that have since been stored in beds of coal, limestone, and granites, may have worn down the rocks on the one hand and built up organic forms on the other, with a rapidity that would now seem hardly conceivable.
